Archived Kit Documentation

The TAPR TICC is a two-channel timestamping counter with better than
60 picosecond resolution and less than 100 picosecond typical jitter.
It has an Allan Deviation noise floor below 1x10-10 for a
one second measurement.

The TICC designed to measure low-rate time intervals, such as the
pulse-per-second signal from a clock or GPS, with very high resolution.
The TICC hardware is a "shield" that mounts on an Arduino Mega 2560
processor board, and the TICC software runs on the Arduino. Data is sent
via USB to a host computer for logging and analysis. The TICC can
currently perform over 100 measurements per second; we believe that
software optimization will ultimately increase the measurement speed.

The TICC can output timestamp data for each channel, or the time interval
between the two channels. The channel inputs trigger with about 1.7 V and
are safe to 5 V. Input impedance is 1 megohm. The TICC requires an external
10 MHz reference clock at nominally +3 dBm, though the input circuit operates
over a wide amplitude range.

The TICC is powered by the Arduino to which is is attached, which in turn
can be powered by the USB cable from the host computer.

The TICC software is open source and available from
github.com/TAPR/TICC. The
repository also includes documentation, data sheets, and other information
on some of the hardware components. The software is undergoing active
development.

Availability

The TICC is available now.

TICC systems purchased from TAPR include the TICC shield and an Arduino 2560
Mega compatible board with TICC software loaded. The systems are tested
for functionality prior to delivery.

Shipping and Handling

Shipping and Handling within the US
will be by USPS Priority Mail.

International shipping costs are calculated as closely as possible. If
the actual cost exceeds the estimate by more than $10.00, TAPR will
contact you to get approval for the additional funds. TAPR uses insured
Priority Mail International, unless the purchaser requires
something else.
